The Schedule referred to in these Ilz-atterrav Patent and making part of the same.

To all whom it may concern Be it knpymthat I, JACOB n. MANNLof the @ity of Chicago, in the count'yof Cook, and State of Illinois, have invented a certain new and improved Diaby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a top view, and

Figure 2, a Vertical cross-section with boiler.

Like letters ref'er tothe same parts in both figures.

The nature and object of my inventionl consist in constructing a diaphragm foi automatic wash-,boilers of a single piece or sheet of' metal, with corrugations or raised passages for the water, so that the diaphragm can belocated near the bottom of the boiler, and economize the space, and also by keeping a thin film of ivater over'the main portion of' the heating-surface, so as to produce amore rapid action and circulation of' the water. These diaphragms, as heretofore constructed, have had a vertical rim or band around them, or have been so f'ar raised at the centre as to keep them a conthe heat is applied, thus keeping a quite large body of water beneath the diaphragm for the heatl to act upon. It is well known that the action of heat on a thin film amount of heat is applied to'a body of' water; and

Myinvention consistsl in a novel mode of applying this principle .to automatic wash-boilers by an improved diaphragm.

To enable others skilled in the art to make and use my improved diaphragm- A represents an ordinary B, a vertical tube; C, the diaphragm; D, the semi-cylindrical or raised water-passages; E, side-openings, through which water is admitted under the diaphragm; v

F, dis harging-holes of the tube; and

oval wash-boiler; v

G, the horizontal portion of the diaphragm.

This diaphragm is made 'to t the form of the boiler used, or nearly so, and around its edge theV openings E are made, asshown at fig. 1 and these openings are made at the ends of the raised water-passages.

The diaphragm is made somewhat conical, the apexv being where the tube or vpipe B is attached, and the raised'passages D pass from the edge into the tube B.

The vouter portion G lies fiat, or nearly so,'on the bottom of the boiler, and the Aconical portion commeuces at the bead or turn I, and is turned up toward the tubewith a slight angle, as shown at fig. 2, so as to carry the water into the tube, but not sufficient to make the space contain any considerable body of'V water between it and the bottom of the boiler.

The'principal portion of' the diaphragm is near the bottom, so that the water presents only a thin film or body to the action of the heat, which makes its action through the tube B very rapid.

There is but one tube, and that is located at the side of the boiler, and the water is discharged through the holes F at the top.

I contemplate making a. portion of the holes lower down on the tube, so as to discharge a portion of the water into and through the clothing.

It will be seen, from this description,.that my diaphragm, with the tube, occupies but very little space in the boiler. v v

Having thus fully described my improvements,

That I claim as new, and desire to secure by Letters Patent, is-

The" diaphragm or false bottom C, when provided with the water-passages D and openings E, to furnish suicient water. for the tube, and leave a thin film of water between such passages, for rapid conversion into steam, substantially asl specified.
